Before, we have featured here several killer apps for Android. Now that there are a growing number of third-party applications that are made for the Android platform, let's take a look at a few of them.

The following are some of the best Android apps that you can get or download for free:

Evernote

One of my favorite iPhone apps has come to Android. Evernote is not your ordinary note-taking application as it will let you sync text, photos, audios, and files across different operating systems minus the hassles.

This app will turn your Android device into a remote control for your computer, which will allows you to run movies and music at a distance. It has all the standard remote control features such as play, pause, rewind, volume controls, and more. Gmote also has a built-in file browser that lets you choose what to play.

A smartphone is not complete without a Facebook app. The Facebook-sponsored application offers a lot of features. You can do almost everything on the Android app that's possible on the full version of the site. What's cool is that you can even add a notification widget to your home screen.

Pandora brings to the table an internet radio app for the Android platform. You can pick your very own music stream: Just start with the name of one of your favorite artists, songs or classical composers and Pandora will create a "station" that plays their music and more music like it.

Twidroid is considered by many as the best Twitter client for Android. It comes in two versions: The "Free" and the "Pro" version. I think the free version has all the necessary features that the pro has that there's really no need for you to upgrade.

Unlike the iPhone, Android doesn't have an official Wikipedia app yet. However, there's Wapedia, an application that will let you quickly access Wikipedia and its content with its clean and intuitive interface.

Astro is a multi-featured file manager that can read images, zip, and tgz files. It can send files as attachments and it also has a search feature. Astro also serves as a task manager that will let you kill those useless background processes.

With Documents To Go, you can view, edit and create Microsoft Word, Excel and PowerPoint files as well as view Adobe PDF files on your Android-powered device. This is really an essential app for people who are always on the go.

If you need a voice recorder app for your Android phone, get Voice Recorder; simple as that. With this app, you can send the audio data as attached file via Gmail. You can also set recordings as ringtones.
